Spectral sensitivity of red and orange eye flies with selectively rescued photoreceptor responses. Normalized spectral sensitivity of red eye (black lines) and orange eye (orange lines) flies with rescued activity of receptors with Rh1, Rh3, Rh4 or Rh5. Modelled visual pigment templates (dashed lines), based on previous estimates^4,40. Error shown is standard deviation. Shading denotes significance between red and orange eye flies using a two-sample Student’s t-test at p ≤ 0.001. For V-log(I) curves, (see Supplementary Figure S1). n = 6 for all spectral sensitivity tests. For statistical test results see Supplementary Data.
